name: linear-sync description: Updates Linear issues based on project-status evidence. Use when asked to sync Linear with code evidence or update issue status.

Purpose

Synchronize Linear issue status with implementation evidence from code repositories. Updates issues to reflect actual development progress based on evidence from /project-status.

When to Use

Apply when user asks:

• "Sync Linear with actual status"
• "Update Linear based on code"
• "Linear issues are out of date"
• "Mark Linear issues as done/in progress"

Important: Only invoke when user explicitly asks to update Linear. This skill modifies Linear data.

Prerequisites

• Linear MCP configured or LINEAR_API_TOKEN in .env.local
• At least one evidence source configured (local repo, GitHub, or Linear)

---

Workflow

Step 1: Get Implementation Evidence

If components specified, invoke /project-status <components>. If no components specified, invoke /project-status for full project scan.

Parse the output table to extract:

• Component name
• Status (Triage, Backlog, Todo, In Progress, In Review, Done, Shipped, Canceled, Unknown)
• Evidence description
• Source

Step 2: Query Linear Current State

Resolve team identifier: Before querying issues, resolve the configured teamName to a valid team:

1. Call mcp__linear__list_teams to get available teams
2. Match configured teamName against team name, key, or UUID
3. Use the matched team's name for all subsequent queries

This allows users to configure any of: team key ("TEAM"), team name ("My Team"), or UUID.

Important: The Linear MCP team parameter only accepts team name or UUID, not team keys. Always resolve keys via list_teams first.

1. Get team's workflow states:

   • Use mcp__linear__list_issue_statuses with the resolved team name

2. For each component, search for matching Linear issues:

   • Use mcp__linear__list_issues with query parameter set to component name

Step 3: Match Components to Linear Issues

For each component from project-status:

Primary: Exact Title Match

• Issue title matches component name (case-insensitive)
• Score: 100

Secondary: Partial Title Match

• Component name appears anywhere in issue title
• Score: 60

Tertiary: Identifier Match

• If component looks like "TEAM-123", query by identifier directly
• Use mcp__linear__get_issue with the identifier

No Match

• Add to unmatched list
• Report in output with option to create new issue

Step 4: Determine Required Actions

For each matched component-to-issue pair:

1. Compare project-status status to Linear issue status
2. Apply status priority ordering (see Status Mapping)
3. Determine if upgrade is needed

Upgrade-Only Rule: Never downgrade status automatically. If Linear shows higher status than evidence, skip the update and note it.

Step 5: Generate Change Preview

Output a preview table showing all proposed changes:

Copy## Linear Sync Preview

| Component | Issue | Current | Proposed | Evidence |
|-----------|-------|---------|----------|----------|
| auth | TEAM-123 | Backlog | In Progress | Feature branch exists |
| dashboard | TEAM-456 | In Progress | Done | PR #78 merged, CI passing |

### No Change Needed
- TEAM-789 (payments): Already at Done

### Skipped (Linear status higher)
- TEAM-111 (analytics): Linear at Done, evidence shows In Progress

### No Linear Issue Found
- notifications: No matching issue

Proceed with updates? (y/n)

Step 6: Request Confirmation

Check for auto-confirm mode:

If LINEAR_SYNC_AUTO_CONFIRM=1 environment variable is set:

1. Display one-time warning:

   Copy⚠️  AUTO-CONFIRM MODE ENABLED
   
   This will create, modify, and cancel temporary issues in your configured
   Linear workspace. All test issues will be:
   - Prefixed with [TEST]
   - Set to Canceled status after testing
   - Auto-archived by Linear after the configured period
   
   Workspace: {workspace_name}
   Team: {team_name}
   
   Consider creating a dedicated test workspace if you're concerned about
   affecting your production workspace.
   
   Proceed with automated write tests? (y/n)
   

2. If user confirms, skip per-operation confirmation and proceed to Step 7
3. If user declines, abort the sync

Normal mode (no env var):

• For any updates: Request explicit confirmation
• For bulk updates (>3 issues): Require "yes" typed confirmation
• User can select individual issues to update or skip

Step 7: Apply Updates

For each confirmed update:

1. Update issue status:

   Copymcp__linear__update_issue(id=issue_id, state=new_state_name)
   

2. Add explanatory comment:

   Copymcp__linear__create_comment(
     issueId=issue_id,
     body="Status updated to [New Status] based on code evidence:\n- [Evidence description]\n- Source: /linear-sync"
   )
   

Step 8: Report Results

Output final results:

Copy## Linear Sync Results

### Updated (2)
| Issue | Previous | New | Evidence |
|-------|----------|-----|----------|
| TEAM-123 | Backlog | In Progress | Feature branch exists |
| TEAM-456 | In Progress | Done | PR #78 merged, CI passing |

### Skipped (1)
- TEAM-789: Linear status (Done) already higher than evidence (In Progress)

### No Match (1)
- notifications: No Linear issue found

Status Mapping

Priority Order (Highest to Lowest)

Mapping to Linear States

Resolving Team-Specific States

Since Linear teams can customize workflow states:

1. Call mcp__linear__list_issue_statuses to get team's states
2. Match by state name first (e.g., "In Review")
3. If no match, fall back to state type (e.g., type "started")
4. Handle teams without "In Review" state by using "In Progress"

---

Safety Rules

1. Never downgrade status automatically - Only upgrade to higher priority status
2. Always add comment explaining change - Include evidence source
3. Require confirmation for all updates - No silent modifications
4. Prompt before creating new issues - Don't auto-create
5. Canceled status requires explicit flag - Use --force to mark as canceled

---

Configuration

Read Linear settings from .entourage/repos.json:

Copy{
  "linear": {
    "teamName": "Team",
    "workspace": "my-workspace"
  }
}

Note: teamName accepts team name ("My Team"), team key ("TEAM"), or UUID.

Authentication

1. Preferred: Use Linear MCP (handles OAuth automatically)
2. Fallback: API token from config file

Environment Variables

---

API Token Fallback (When MCP Unavailable)

When Linear MCP is not available (e.g., in automated tests), fall back to direct GraphQL API calls using LINEAR_API_TOKEN from .env.local.

MCP Detection Protocol

1. Attempt MCP tool call (e.g., mcp__linear__list_issue_statuses)
2. Check response:
   • Success → Continue using MCP
   • Failure/not available → Use API token fallback

GraphQL Mutations

Update Issue Status:

Copymutation IssueUpdate($id: String!, $stateId: String!) {
  issueUpdate(id: $id, input: { stateId: $stateId }) {
    success
    issue {
      id
      identifier
      state { id name type }
    }
  }
}

Curl example:

Copycurl -X POST https://api.linear.app/graphql \
  -H "Authorization: $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "mutation($id: String!, $stateId: String!) { issueUpdate(id: $id, input: { stateId: $stateId }) { success } }",
    "variables": {"id": "issue-uuid", "stateId": "state-uuid"}
  }'

Create Comment:

Copymutation CommentCreate($issueId: String!, $body: String!) {
  commentCreate(input: { issueId: $issueId, body: $body }) {
    success
    comment { id }
  }
}

Curl example:

Copycurl -X POST https://api.linear.app/graphql \
  -H "Authorization: $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "mutation($issueId: String!, $body: String!) { commentCreate(input: { issueId: $issueId, body: $body }) { success } }",
    "variables": {"issueId": "issue-uuid", "body": "Status updated based on code evidence..."}
  }'

Get Team States (to resolve state name → ID):

Copyquery TeamStates($teamId: String!) {
  team(id: $teamId) {
    states {
      nodes { id name type }
    }
  }
}

Write Test Safety

When running automated tests that create/modify Linear issues:

1. Prefix all test issue titles with [TEST]
2. Set test issues to Canceled status after verification
3. Linear auto-archives canceled issues per workspace settings

Error Handling

Linear MCP Not Available

Copy> Linear MCP not available. Ensure Linear MCP server is configured.
> See: https://linear.app/docs/mcp

Team Not Found

Copy> Linear team "TEAM" not found. Check `teamName` in `.entourage/repos.json`.

Permission Denied

Copy> Cannot update issue TEAM-123: Insufficient permissions.
> Check your Linear role allows issue editing.

State Not Found

Copy> Cannot find state "In Review" in team TEAM.
> Available states: Triage, Backlog, Todo, In Progress, Done, Canceled
> Using "In Progress" instead.
